It is characterized in that it includes; pressure distribution stage (80).

A plurality of spray ducts are installed in the processing space 11 inside the deodorizing chamber 10, and the number of spray ducts varies depending on the deodorizing capacity of the deodorizing chamber 10. In this embodiment, three air injection ducts are extracted and described by assigning reference numbers 1, 2, and 3.

In the processing space 11, a process of deodorizing the odorous components contained in the odorous gas is performed, and in the exhaust pipe 12, the deodorized and purified air is exhausted. At this time, an exhaust fan 13 for forming a negative pressure is installed in the exhaust pipe 12 to effectively exhaust the air, and management is possible through the inspection window 14 installed on the side.

The pressure distribution stage 80 is installed on the bottom of the processing space 11 in the middle between the first, second, and third injection ducts 30, 30', and 30" to prevent the injection of deodorized gas from the mutually adjacent injection ducts. The pressure distributing stage 80 has a width that decreases toward the upper side from the processing space 11, and more specifically, has circumferential surfaces 80a that are immersed inward on both sides.

For example, when the odorous gas is injected from the ejection grooves 31 of the first injection duct 30 and the second injection duct 30', the ejection directions of the odorous gas are opposite from the injection grooves 31 facing each other. am. Therefore, the injection pressure for injecting the odor gas in the first and second injection ducts 30 and 30' is added at the center of the first and second injection ducts 30 and 30' to the injection pressure in the injection groove 31. compared to at least twice as much. The injection pressure added in this way is directed in the opposite direction to the injection pressure generated in the injection groove 33 of each of the first and second injection ducts 30 and 30', and as a result, the first and second injection ducts 30 and 30 ') Acts as a force that obstructs the ejection of the odorous gas from each injection groove 33, preventing the odorous gas from being sufficiently injected into the cleaning liquid zone Z.

In the present invention, in order to solve this problem, a pressure dispersing stage 80 is installed in the center between the first, second, and third jetting ducts 30, 30', and 30", and this pressure jetting stage 80 The odorous gas injected from the adjacent spray groove 33 is guided to the upper side by the pressure distributing stage 80 so that the spray pressure applied in the direction facing each other is not added, and accordingly, the first, second, and third This is to prevent the force that hinders the spraying of the odorous gas from acting on the spraying ducts 30, 30', and 30".
